Description

 Thinkre™ reinforced proton exchange membrane is produced by using PFSA resins with appropriate molecular weight and ion exchange capacity through tape casting process, its similar to N- 324. It is widely used in electrolytic chlorine dioxide generator,copper recovery by etching solution, gold salt preparation, amino acid refining, caustic soda preparation, electrodialysis, water treatment and other electrolytic industries. 

characteristic

Excellent tolerance to strong acids (H₂SO₄, HCl), weak bases or a low concentration of alkali, and highly oxidative environments (Cl₂, O₃).

High tear resistance, preventing localized perforation (pinholes) under hydraulic pressure fluctuations.

Application

  • Chlor-alkali electrolysis (low-concentration), Chlorine dioxide generators, Electrodialysis (ED), and heavy metal recovery (e.g., Copper/Nickel etching solution recycling).
  • Nuclear chemical engineering (e.g., Uranium valency regulation), high-pressure electrochemical synthesis, and harsh environment waste acid purification.
  • Salt-splitting (Sodium sulfate electrolysis), and advanced Electro-deionization

   Measurements taken with membrane conditioned to 23°C, 50% RH for 24h.

   A base titration procedure by using the caustic soda measures the equivalents of sulfonic acid in the membrane, thus calculating the acid capacity or equivalent weight of the membrane.
